Be it knownthan I, GEORGEG. MAYEN:

SCHEIN, a citizen of the United States, residing at Sunnyside, in thecounty of .Yakima and State of Washington, have invented certain new anduseful Improvements inHaylv Derricks, of which the following is aspecification.

, My invention is a derrick ,usedV for stack!` ing hay, straw, and thelike, and is known as the flying-dutchman derrick; and it consists inaframe having a braced central vertical post and a swinging beamjournaled on'- l represents Ytwo sills, the under edges yof their ends'being beveled off, so as to round themupwardly.2representscross-beamsrigidly secured to the said sills. ExtendingVertically from the oentralcross-beam is a oenytral braced post 3, whichabout two-thirdsof-- the distance from its lower endhas a shoulder 4,and resting on said shoulder is a cir,-4 cular bearings', and from thesaid shoulder Y, the said post is cylindrical, forming a cylindricalbearing 5. tion of this cylindricalbearing 5 and against the upper ofthe circular vbearing 4:' isI a collar 6, having extending therefrom atVan angle of about forty-five degrees two armsockets 7,and,extendingfrom'these armsockets at the same anglefare securedtwobraces 8 and secured to the upperjends ofi these two braces horizontallyand .ona line Vexactly atright anglesto v the post 3 isfa swinging beam9, andthrough the center of" this swinging beam 9 is'aperforation 1Q,and extending downwardly through said perforation and into the upper endof the cylindrical bearing is a headed `bolt 11. 'Depending from eachend of said swinging beam and from the under face thereof is abearing12, and in each of said'bearings is `journaled a pulley 13.Depending from the extreme of Vorkng on the lower por.

the tongue part 2O has in its'lower end a de-i pression 21in'which fitsthe catch 19. The

The

thereto a double and a pair of single'trees25.- Saidcable runs back andunder a pulley 26,'

which-is journaled in a keeper 27,!securedto2 the upper face of one'ofthe beams, and'runs up over the pulleys'13 andv then hangs downr" wardlyand bearsin its swinging end 'a bundleofstraw28. v The operation of myinventionfis:described 'as follows; The rst thing is to havethefmachineplaced in proper position.` 'On` onecor-` ner of the fr'amejs theflock17, towhich issej Y 'cured the cable 15.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is` l 1. The combination of a base-frame, consistingof side sills 1, and cross-beams 2; a braced central post 3, havingabout two-thirds of the way from its face, a shoulder 1i, and lo restingon said shoulder, a collar 4', the balance of said post terminating in acylindrical beariug; a collar 6, encircling said cylindrical bearing 5,and resting on said collar just named; arm-sockets 7, extending up- [5wardly and at au angle of about forty-iive degrees from said post; arms8, secured in said sockets, and extending upwardly at the same angle; aswinging beam 9, secured horizontally to the upper ends of said arms 8,zo and at right angles to said post; a bolt 11, passing through aperforation 10, in the beam 9, and into the upper end of the cylindricalbearing 5; a lock 17, secured to one corner of the base; a cable, oneend secured to the tongue part 21, of said lock, and the other to oneend of the beam; a hoisting-cable 24, having a doubletree secured to itsfree end; said cable passing under a pulley 13, secured to one end ofthe beam 9, and over another 3o pulley 13, secured in the other end ofsaid beam, and thence downwardly, and adapted to be secured to a slingor grapple-hooks, and an operating-cable having one end secured to thehoisting-cable, near the doubletrees, the other end secured to the upperend of the tongue part 2l, of the lock, substantially as shown anddescribed and for the purposes set forth.

2. The combination of a base-frame; a vertical central braced post,having some distance from its lower end, a shoulder; a circular bearingresting on said shoulder, the balance ot' said post terminating in acylindrical bearing; a collar journaled on said cylindrical bearing andresting on said circular bearing; arms extending upwardly at rightangles from said collar; a swinging beam secured horizontally to theupper ends of said arms; a bolt passing down through the center of saidbeam into the top of said cylindrical bearing; a lock secured to onecorner of said base; a cable, one -end secured to the tongue part ofsaid lock and the other to one end of said swinging beam; ahoisting-cable, having a doubletree secured to one end, said cablepassing under a pulley secured to the base-frame, passing thence up-overpulley se cured to the under face of said cross-beam, and thencedownwardly, and adapted to be secured to a sling or grapple-hooks, andan operating-cable, one end secu redto the hoisting-cable and the otherto the upper end of the tongue part of the lock, substantially as shownand described and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
